REVOLVING GUARD FOR LOCOMOTIVE COW-CATCt-LERS.

SPECIFICATION forming part of Letters Patent No. 288,788, dated November20, 1883.

Application filed February 5, 1883. No model.)

1'0 all whom, it may concern:

Be it known that I, J our D. FISK, of Hartford, in the county ofHartford and State of Connecticut, have invented new and ImprovedRevolving Guards for Locomotive Cow-Catchers, of which the following isa full, clear, and exact description.

The object of my invention is to provide new and improved revolvingguards for locomotive cow-catchers, to throw snow, stones, ties, orother obstructions from the track.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure'l is a plan view of a cow-catcher provided with the revolvingguards, the cowcatcher being shown in dotted lines, and the prongs beingomitted from the guard-shafts. Fig. 2 is a longitudinal sectionalelevation of the same. Fig. 3 is an enlarged longitudinal view of partof the revolving guard. Fig. 4 is a crosssectional elevation of thesame. Fig. 5 is a front view of a modification, and Fig. 6 is a sideview of another modification.

A shaft, A, is journaled in jaws a, projecting from the front side ofeach bottom rail, B, of a cow-catcher, G, in such a manner that the saidshafts will be parallel with the said bottom rails. The shafts A areprovided on the adjoining ends with cog-wheels D engaging with beveledcog -wheels E, made integral with or attached to the sides of a smallsprocket-wheel, F, journaledin the front lower part of the cowratcher. Adrivingchaiu, G, passes over a sprocket-wheel, H, on the front axle, J,of the locomotive. On the shafts A a series of collars, K, are mountedand held on the same by screws L or other suitable devices, whichcollars are provided with opposite blades M, about three inches longfrom the center of the shaft, and about two inches wide. The collars areso arranged that the ends of the blades form spiral lines, and so thatthe blades will be about two inches apart. The ends of the bladesproject about two inches below the bottom rails of the cow-catcher.

When the locomotive is in motion, the sprocket-wheel H on the front axleoperates chain G, which in turn operates the sprocketwheel F, from whichthe motion is transmit ted to the shafts A, the same being revolved inthe direction upward and toward the cowcatcher, so that their blades Mwill throw objects against which they strike from the catcher. Therevolving guards formed by the shafts A and blades M will throw snowfrom three to eight or nine inches deep, or stones, ties placed on thetrack, and other like obstacles, from the track, so that the saidobstacles can under no circumstances pass under the cow-catcher, and arethus prevented from throwing the locomotive from the rails.

If desired, the blades or wings M can be made tapering and curved, asshown in Fig. 5, or they can be twisted like the blades of ascrew-propeller, as shown in Fig. 6, or be arranged parallel with theshafts. In fact, the blades may be of any suitable length and width, andbe arranged radially close together or more or less apart on the shafts,at any angle therewith, or with their ends describing a spiral line, asabove described.

In place of an angular cow-catcher,a straight cow-cateher can be used. Asingle spiked or pronged shaft is then journaled on the same, whichshaft is provided with a central single cog-wheel, which is operated bythe. cogwheel E.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. A cow-catcher having the shafts A A journaled in the jaws a, providedwith bladed collars K, and projecting from the front side of andparallel with each bottom rail, B, in

combination with the bevel cog-wheels D E, thesprocket-wheels F H, thechain G, and

the axle J, as and for the purpose described.

2. The blades mounted upon the shafts A by collars K, and having theirends arranged in spiral lines, as and for the purpose specifled.

3. The combination, with a locomotive cow catcher, of the shafts A,journaled in front of the lower part of the same, devices for rotatingthe said shafts from an axle of the locomotive, and of collars K,provided withblades or wings M, and mounted on the shafts A,substantially as herein shown and described, and for the purpose setforth.

* 4. The combination, with a locomotive COW-021361161, of the shafts A,journaled in around the shafts, substantially herein front of the lowerpart of the same, devices shownand described, and for the purpose setfor rotating the said shafts from an axle of forth.

the locomotive, and of collars'K, provided JOHN D. FISK. [LS1 5 withblades or Wings M, which collars are \Vitnesses:

mounted on the shafts in such a manner that MAHLON R. WEST,

the outer ends of the blades form spiral lines JOHN XV. OOOGAN.
